Engineering & Design to Mitigate Riverine & Coastal Flooding
Identify and address flood hazard areas in existing communities and proposed developments
WithersRavenel specializes in comprehensive flood studies. Using detailed hydrology and hydraulic modeling, we design new or upgraded stream crossings for vehicles, pedestrians, and utilities in areas with a history of flooding or in preparation for future upstream development. The crossings can include customized culvert designs fitted to the unique characteristics of a stream, creek, or river.
Comply with FEMA documentation requirements
Projects located within floodways require an engineering analysis to determine if the project will have any impacts, particularly adverse ones. WithersRavenel’s stormwater engineers can prepare No-Impact Certifications and No-Rise Certifications as appropriate for your project.
Inform prospective buyers, sellers, and developers of potential flood risks
We work closely with clients, local communities, and FEMA to modify Flood Insurance Rate Maps (FIRM) to accurately represent existing conditions or new developments.
